Hello.

Thanks for feedback, Mathias!

There is no such library Boost.Move. Do you mean to implement move like 
Boost.Thread does?
If so. I think it is not necessary because one can just write 
"underlying_resource_type" instead of "thread_move_t" and ".release()" 
instead ".move()".

If copy constructor or move constructor can throw an exception the only 
function that works incorrect is release. There is no way to implement 
it in exception safe manner in this case.

Note that usually this is not a problem. Usually 
underlying_resource_type is not something complex, but rather it is just 
int or void* or something like that. So its copy and move constructors 
do not throw exceptions.
